conda install 中途打断出现ERROR REPORT
conda install由于Ctrl C等中途打断，下次安装时出现错误如下报告：

并且询问是否发送错误报告：
Would you like conda to send this report to the core maintainers?
[y/N]:
之后每次安装都会出现这个错误报告，是因为中途打断文件读写意外停止
可以使用conda clean命令净化anaconda：
Options:
usage: conda clean [-h] [-a] [-i] [-p] [-t] [-f]
[-c TEMPFILES [TEMPFILES ...]] [-d] [--json] [-q] [-v] [-y]
-a, --all
Remove index cache, lock files, unused cache packages, and tarballs.
-i, --index-cache
Remove index cache.
-p, --packages
Remove unused packages from writable package caches. WARNING: This does not check for packages installed using symlinks back to the package cache.
-t, --tarballs
Remove cached package tarballs.
-f, --force-pkgs-dirs
Remove all writable package caches. This option is not included with the --all flag. WARNING: This will break environments with packages installed using symlinks back to the package cache.
-c, --tempfiles
Remove temporary files that could not be deleted earlier due to being in-use. Argument is path(s) to prefix(es) where files should be found and removed.
必须选择一个option
一般使用：
conda clean --tarballs
删除tar包即可
若还是不行，则删除所有：
conda clean -a
